S. GRANDT, OF

DISPENSING TOP FOR CONTAINERS.

Application filed September 11, 1925. Serial No. 55,657.

This invention relates generally to a construction of dispensing topsfor containers and more particularly to a dispensing top or closuremember for/collapsible tube containers.

A general object of the invention is to provide a closure member forcontainers more particularly of the collapsible tube type in whichprovision is made for producing a tight or closely sealed effect whenthe device is in non-delivering condition.

The invention includes a delivery or discharge nozzle for the tubevcontainer having a conical formation with a discharge port in one of theside walls thereof. A closure member is fitted 'to the conical dischargemember with the edge thereof spun or upset into locking relation withthe base of the conical discharge member, the 010 sure member beingrotatable about the discharge member on which it is supported to therebybring an opening in the side wall thereof into and outof registrationwith the delivery opening in the nozzle member.

In a prefenred embodiment of the inventionthe discharge member and theclosure member have an unsymmetrical or eccentric formation designed toroduce a binding or he walls of the members immediately about the openinwhen the openings are moved out of re istration with each other. Thisresults in t e attainment of a complete and adequate sealing effect inthe non-operative position of the closure member so that the mererotation of the closure member in either direction to non-operativeposition has the effect of closely sealing the edges of the opening tothereby preserve the contents of the container.

Other features of the invention will be hereinafter 'referred to.

Referring to the drawings for a more detailed description of, theinvention, a collapsible tube container 10 is shown in Figure 1, thecontainer being provided with a dispensing top 11 to which the inventionhereinafter described is directed. The dis pensing top 11 of thecontainer 10 is made up of a discharge nozzle member 12 formedintegrally with the shoulder 13 of the container and which has a conicalformation.

14 formed in the nozzle member 12. The

relation of the cap or closure member 16 to the nozzle member 12 is suchthat the member 16 can be rotated on its sea-t through an angle or partof a revolution indicated by the arrows in Figure 3 of the drawing.

The nozzle member 12 is provided with a discharge opening 18 which takesthe form of an elongated slit extending axially of one of the faces ofthe conically-shaped nozzle member. A corresponding port or opening 19is formed in the cap or closure member 16, the ing somewhat smaller inits lateral direction than the opening 18 in the nozzle member 12. Theopening 19 in the cap member 16 is adapted to be brought. into or movedout of register with the opening 18 in the nozzle member 12 uponrotation of the cap member 16 in the manner described.

In order to bring about a desired or necessary sealing effect which willcompletely close the openings in the di ensing member when ininoperative position, the dispensing top portion of the container isformed in an unsymmetrical or eccentric formation as is clearly shown inFigures 2, 3 and 4 of the drawing. Referring again to opening 19,however. be-.

Figure 2 of the drawing it will be seen that the cap member 16 is sodisposed that the opening 19 therein in alinement or register with theopening in the nozzle member 12.. With this disposition of the parts itwill be seen that the base portion of the cap member 16 is spacedsymmetrically about its length from the corresponding shoulder or baseportion 15 of the inner nozzle member 12. On the other hand, referringto Figure 4 of the drawing, it will be seen that when the cap or closuremember 16 has been rotated through a position such as will remove theport 19 from registration with the port 18, the base portion of the capmember 16 is brought into close contact or engagement with the baseportion of the-nozzle member 12 in the vicinity of the port 18 while atthe opposite side of the top member the cap mem er 16 is spaced at aslightly increased distance from the enclosed base portion 15 of thenozzle member 12.

The general result of this disposition of parts is to force the innersurfaces of the cap member 16 which lie adjacent to the port 19 intoclose engagement with the contiguous outer surfaces of the nozzle member12. This has the effect of producing a tight or closely fitted relationof the parts which provides an effective sealing effect and preventsevaporation of volatile constituents of the contents of the containerwhen the dispensing top is turned to inoperative position.

Reference has already been made to the smaller size of the port 19 inthe cap member 16 as compared with the size of the port 18 in the nozzlemember '12. The purpose of this is to provide a non-registration of theedges of the openings 18 and 19 as is clearly shown in Figure 3 of thedrawings, when the ports are in registering positions.

. By this arrangement a pronounced shearing or cutting effect isachieved upon the region of material extending through the ports at thetermination of a dispensing operation of the containers. This shearingoperation is rendered particularly clean-cut by the nonrcgistration ofthe parts referred to so that a clearing action of the ejected materialis provided which prevents the accumulation of residues or remnants ofmaterial in or about the discharge ports.

In order to facilitate the operation of rotating the cap or closuremember 16 the outer surface of the cap member 16 is preferablylongitudinally corrugated or grooved as at 20 to facilitate grasping ofthe closure member by the fingers of the user.

In Figures 5 and 6 of the drawing there is shown a modified form of theinvention wherein the parts are shown in av symmetrical or conicalrelation as distinguished from the unsymmetrical or eccentric relationas shown in Figures 1 to at of the drawing.

In this form of the invention the nozzle member 21 has a trulysymmetrical, conical formation and the cap or closure member 22 which isfitted in rotative relation to the nozzle member 21 has, in like manner,a conical formation such that the cap member 22 can be rotated through afull movement of revolution about the nozzle member 21 upon which it isseat-ed. While this form of the invention does not rovide the specialseating effect achieved in the construction shown in Figures 1 to 4 ofthe drawing, nevertheless, the dispensing top or closure thus providedis capable of useful application and is a substantial improvement overdevices for this general purpose heretofore known and used.
